If you are talking to a station using a repeater, how would you find out if you could communicate using simplex instead?
- A By asking a third station to confirm it receives you both
- B By checking if you can clearly receive a more distant repeater
- C By asking the other station to move 10 kHz away to test the path
- D By checking if you can clearly receive the station on the repeater's input frequency
Correct answer: D — By checking if you can clearly receive the station on the repeater's input frequency. From the official ISED question bank, verified word for word.
Why
A repeater listens on one frequency and talks on another, so to see if you can talk directly without it, you must listen on the repeater's input frequency where your voice would go. The full explanation — and one for every question — is in Pro.
